DISHWASHING MACHINE.

Application filed November 9, 1921. serial No. 513,960.

This invention relates to improvements in dish Washing machines. a v

The objects of this invention are to provide a dish washing machinewhich is operated by a fluid motor with means of communioation between the motor and a dish washin machine casing so as to increase the circulation of the cleansing fluid; to provide a fluid actuated motor that is actuated by a jet of air which is permitted to circulate through the main casin of the machine; to provide an improved rain connection for the main casing and the motor casing; to

provide an improved means of rinsing anddrying the dishes after the washing operation; and to provide a machine that can be operated by merely attaching the same toa source of air supply'and which possesses a high. degree of efiiciency; and finally to provide anim roved basket structure 'for holding the dishes, together with means for supthe basket. i

Other objects of the invention will appear from the following description and claims when considered together with the accompanying drawings. v

Fig. 1 is a side elevation of my machine showing the drain valve in section; l*ig.. 2 is an end elevation of my machine; Flg. 3 is a view partly in elevation and partly in transverse section; Fig.4 is a vertical section through the'dish container; and Fig. 5 is a section through the motor.

The casing 1 which is adapted tocontain the rotary basket for holding the dishes is provided with the bottom 2 which supports the basket thereon by means of the spider 3 in which rests for pivotal movement the stem 4: secured near its lower end to the porting the same for rotary movement in plate 5 attached to the dish shaped bottom 1 member 6. The bottom 6 is perforated as at 6. The lower part of the basket is indicated in a general way at 7 and is supported in the peripheral portion of the dish member 6 for rotation therewith, the upper part of the basket being indicated at 7'.- An annular rack member 8 is secured about motor through mechanism to be later described. The dish shaped cover 10 rests upon the upper end of the upper basket port1on 7 and is provided at its central portion with the plate 11 through which extends the stem 4. The outer cover 12 has frictional engagement at 13 with the upper end of the casing 1 and is provided also with the. socket plate 14. secured in its central portion for engagement with the upper end of the stem 4. In this way. the\. stem 4 is steadied through its upper portion to prevent any wobbling of the same during its rotation.

The auxiliary casing 15, which encloses the motor, is secured by means of the flanges 16 and bolts 17 to the correspondingly formed flanges 18 on the wings 19 secured at 20 to the sides of the main casing 1 The main casing is provided with an opening indicated at 21 at this point while a plate'22 is secured between the flanges 16 and 1-8 so as to separate the auxiliary casing 15 from the opening 21 in the side of the main casrug. An opening 23 is however provided in the upper part of the plate 22 so as to afford communication between the main and auxiliary casings for circulation of 'is suitably journalled in the bearing 26 secured to the wall 22. Secured also to the inner end of the hollow shaft 25 by means of screw threaded engagement indicated at 27; is the member 28, which carries the fan- 29 and which has extending outwardly therefrom, and therethrough the pipes 30 and 31 of different lengths as indicated in the drawing, and which carries also at its extreme inner'end the pinion 32 for meshing engagement with the annular rack 8. As indicated in Fig. 3, the member 28 is hollowed out so as to afford communicationbetween the passage through the hollow shaft 25 and the tubes 30 and 31 for the purpose which will later appear. The journal hearing 24 is provided also with the screw threaded nipple 33 to which canbe attached a pipe or tube for the supply of hot water point between the journal bearings 24 and 26 is the disc 34 upon the opposite faces of which are secured asindicated at 35, the plates having the diverging portions 36 and the parallel extending portions 37 Between and secured to these plates are the grooved strips 38 which are formed with pockets indicated at 39. Attached to the one side portion of the auxiliary casing isthe compressed air pipe 40 which opens at a point in one of the lower quadrants of the rotary path of movement of the rotor,

so as to force'air into-the pockets 39 in succession and to partially displace the water contained in such pockets by air. In this way the replacement of the water with air causes an overbalancing of the rotor with the result that the heavier portion of the same will descend while thelighter portion which contains the air will ascend, thereby causing rotation of the rotor about the shaft 25. Such air as is forced" into the plockets 39""will graduallyescape therefrom t rough the passages 41 and 42 and will rise through the auxiliary chamber and find its way through the opening 23 into the main of the machine, thereby increasing the c1r-' culation of both the air and the cleansing fluid. It is to be understood that the air forced into the main casing of the machine can escape past the cover.

Secured to the underside of the bottom is the bracket 43 through which extends an opening 44 in a horizontal directionand also an opening 45 leading fromathe main casing. These communicating openings are controlled by conical valve member 46 having the open sides 47, 48 and 49 and the closed or full side 50. The one side of the bushing 43 has screw threaded engagement at 51 with the pipe52 which is connected at its other end at 53 with the auxiliary casing for discharge of the fluid therefrom.

The other side of the bushing 43 has screw 1 nation of a casing adapted to contain cleansthreaded engagement at 54 with the discharge pipe 55 through which can be dis charged the fluid from the main casin as well as from the auxiliary casing. structure constitutes a multiple-way valve which can be so adjusted as to permit dis. charge of-the cleansing fluid from the main casing upon completion of the dish washing while at the same time preventing discharge of fluid from the auxiliary casing. At such time the full portion 50 of the valve closes the pipe 52 while the opening 45 is in communication with the discharge pipe 55. The valve stem 56 for manipulation of the valve 44 extends out beyond the side wall of the main casing to be operated by the handle 57 From the above it will be seen that when uch the dishes are placed in the rack of the main casing, cleansing fluid, as for instance soapy water, can be run into the main casing either through the top thereof or through the pipes 30 and 31. When the proper level of fluid has been obtained the coverscan be applied to the main casing and the jet of air will be turned into the pipe v40 so as to start the motor, the cleansing fluid having already filled the auxiliary casing through the communicating opening 23. As before explained the displacement of 'liquid'by' air in the pockets 39 will cause rotation of the rotor and consequently rotation of the fan, 29 and the pinion 32. The meshing of the pinion 32 with the annular rack 8 will cause rotation of the frames 7 and 7 so as to subject the dishes to the cleansing operation. Then upon completion of the washing operation the valve in the bottom of the easing will be turned so as to permit discharge of the fluid from the main casing and at the same time retain the fluid inthe auxiliary casing so as to continue the motor in operation. Then upon attachment of the hot water pipe or tube to the nipple 33, the dishes in the frame-will be rinsed by the spraying of hot water thereupon throu h.

operation of the motor so as to thoroughlysubject all of the dishes to'the drying by the hot air. Then upon completion of the mg operation the discharge valve can e turned so as to discharge the fluid from the auxiliary casing. 7 What I claim is: 1. In a dish washing machine, the combiing fluid, a sectional dish supporting frame rotatablymounted in said casing, an annular rack on one of the sections of said frame and affording seating engagement between said sections, a pinion meshing with said rack forrotation of said frame, and means for operating said pinion.

2. In a dish washing machine, the combi-.

nation of a main casing adapted to contain 1 cleansing fluid, a dish supporting frame rotatably mounted in said casing an auxiliary casing having communication with said main casing, whereby said cleansing fluid mikyflow from one casing into the other, a u1d actuated rotor in said auxiliary casmg having operative connection with said frame for rotating the same, a discharge connection for said casings, and a multiway valve controlling said discharge connection whereby said main casing can be drained without draining said auxiliary casing.

3. In a dish washing machine, the combination of a main casing adapted to contain cleansing fluid, a dish supporting frame rotatably mounted in said casing, on a vertical axis, an auxilary casing associated with said main casing, a rotor in said'auxiliary casing having operative connection with said frame for rotating the same, and a fluid supply connection for said main casing through the axis of said rotor, said fluid supply connection having discharge mem bers arranged to direct the fluid transverse- 1y of the path of rotation of said frame.

4. In a dish washing machine, the com- 20 bination of a main casing adapted to contain cleansing fluid, a dish supporting frame rotatably mounted in said casing on a vertical axis, an auxiliary casing associated with said main casing, a rotor in said auxiliary casing having operative connection with said frame ,for rotating the same, and a fluid supply connection for said main casing through the axis of said rotor. said fluid supply connection having discharge members arranged to direct the fluid transversely of the path of rotation of said frame and at points unequally distant from the axis of said rotor.

In testimony whereof I hereby afiix my 35- signature.
